Computer Based Information Systems (CBIS) have become pervasive in modern organizations. The MISrnliterature has always treated IS a support tool rather than a core requirement for a modern organization. Butrnthe latter is probably a more realistic picture of the role of CBIS in organizations today. This paper arguesrnfor this perspective. It argues that CBIS help organizations overcome cognitive limitations of humanrninformation processing and are necessary to meet the performance goals and assist in the decision-makingrnprocesses of the organization. It points to the inherent complexity, fast rate of change, and uncertainty inrnmodern environment and argues that the information processing requirements posed by these conditionsrnprecludes not using a CBIS if the information processing is to be done in an efficient and effective fashion.rnGiven that a CBIS is necessary for organizations, it has important implications in areas like organizationrndesign, business process design, and CBIS development and deployment. It is hoped that this paper will putrnforward the idea that is explicated in the mainstream literature and create impetus and discussion for furtherrnresearch.
